This supplement is so strong that you can feel it beginning to clear your lungs in 20 minutes. If you take many supplements at a time and aren`t sure if you remembered to take this one, just wait 20 minutes and you`ll know. Helps clear up nasal congestion and post-nasal drip as well. It would likely help motivate a smoker to quit smoking in the early stages and do a good job of cleansing and recovery over time.

It contains a good combination of mucilaginous and expectorant herbs. Most importantly, I can quickly feel the anti-spasmodic effect of Black Cherry bark and get relief from whooping cough (which I termed "machine-gun" cough that tickles till you choke). Because of Long pepper and Cassia Twig (cinnamon), those with heat-cough (where you feel heat in your throat or head) may do better with half the dosage. Those with prolonged and lingering cough can also take half the dosage to tone the lung toward full recovery. This formula is too acrid (spicy) and not suitable to be used alone when there is high fever.
